Zero Trust Security

Zero Trust Security represents a paradigm shift in cybersecurity, moving away from traditional perimeter-based defense models to an approach where no user, device, or application is inherently trusted. This book provides a comprehensive guide to understanding and implementing Zero Trust Architecture (ZTA), covering identity management, network security, endpoint protection, cloud security, and compliance requirements.The book begins by introducing the Zero Trust model, explaining how it evolved from traditional cybersecurity approaches and why it is critical for modern enterprises. It then explores the core components of Zero Trust Architecture (ZTA), including least privilege access control, microsegmentation, and continuous authentication mechanisms.A major focus is placed on Identity and Access Management (IAM), emphasizing multi-factor authentication (MFA), privileged access management (PAM), and adaptive security controls.
